Sessions at OSCON 2011 with slides on Tuesday 26th July

You've heard that Functional programming (FP) is good for concurrency. Mastering FP will improve all the code you write. FP changes practices like TDD; learn how design is more structured and tests are more precise. See why FP-style functions and data structures are actually more reusable than objects. Leave with new tools that eliminate bloat, improve code quality, and speed development.

We'll talk about the roles of A/B testing and similar techniques in web applications, examine an open-source A/B framework for PHP, and present general design ideas that can be applied to building similar systems using other technology stacks.

Clue: I won't say "no" and sit in silence for 3 hours. This workshop I will go through a number of HTML5 and (new) non-HTML5 technologies and show you, with working code, how these technologies can be used in production today.

Vital strategic advice for anyone involved in running a tech business, big or small. In today’s computing world, it can feel like we're drowning in wave after wave of new trends. This sea of concepts is simply the evolution of our industry from a product to a service based economy. Learn how to navigate this change to your advantage, and find a balance between the present and the future.

An application that works great in development and test can be crushed by real-life deployment. Don't let your project be one of them. In a hands-on workshop, fix a (realistically) broken Django example so that it can hold its head high under load.

SugarCRM is designed as a Rapid Application Development platform. In this half day tutorial you'll learn how to build a business application on the Open Source SugarCRM platform.

Ganeti is a cluster virtualization management software tool built on top of existing virtualization technologies such as Xen or KVM and other Open Source software. This hands-on tutorial will give an overview of Ganeti, how to install it, how to get started deploying VMs, & administrative guide to Ganeti. The tutorial will also cover installing & using Ganeti Web Manager as a web front-end.

Quick and effective jump start for using Apache Solr, the Lucene-based search server. Solr powers the search and discovery systems of sites such as Zappos, Smithsonian's collections, The Motley Fool, Orbitz, and many many others. This three hour session will give you the basics to immediately begin using Solr on your own data.

Security and open source have a history that goes back to an era long before computers. The story begins with 19th century linguist Auguste Kerckhoffs and his principle that security isn't found in obscurity. We will cover the intertwined and lesser-known history of security and open source from then to now, with his big idea as a guiding principle, making a compelling argument for open source.

Studying our most popular open source projects we find that 9 are significantly larger, roughly 10x, than any of the other projects. These "XtraLarge" projects have some notable characteristics that are interesting to anyone wanting to grow his/her open source project to similar magnitude and importance. Ex: All are collaborative non-profit community projects, with modular software architectures.
